利用准维卷吸模型计算汽油机的质量燃烧率

在零维计算模型的基础上，建立了适用于汽油机质量燃烧率计算的准维紊流卷吸模型，力图反映压缩及燃烧过程中紊流参数对汽油机燃烧过程的影响，文中给出了模型的物理意义、数值求解过程，并通过对子模型的验证及由此进行的示功图计算验证，表明该模型较零维模型有更清晰的物理意义和实作价值。

CALCULATING THE MASS BURN RATE OF SPARK-IGNITION ENGINES BY QUASI-DIMENSIONAL TURBULENT ENTRAINMENTMODEL

A quasi-dimensional turbulent entrainment model developed from zero-dimensional oneis presented in this paper,which introduces the fundamental physical quantities of turbulenceduring the compression and combustion process into the calculation of the engine workingprocess.The physical meaning of the model and the numerical solution are given.The match-ing calculation for engine's indicated diagrame shows that this model has clearer physicalmeaning and more valuable than the zero-dimensional one.
